Privacy Policy

Last Updated: October 13, 2026

1. Introduction

This Privacy Policy explains how ZeraBooks (“ZeraBooks”, “we”, “our” or “us”) collects, uses, discloses and protects personal information when you visit zerabooks.com or use the ZeraBooks web application, including the General Ledger, the Converter and the Ask Zera assistant, and our bookkeeping and enterprise services (together, the “Service”). Capitalized terms not defined here have the meanings given in our Terms of Service.

ZeraBooks is operated from British Columbia, Canada. We handle personal information in accordance with Canada’s Personal Information Protection and Electronic Documents Act (PIPEDA) and British Columbia’s Personal Information Protection Act (PIPA) where they apply, and we provide the rights described below to individuals covered by the EU and UK General Data Protection Regulation (GDPR) and U.S. state privacy laws such as the California Consumer Privacy Act (CCPA), where those laws apply to us.

Accountability: our founder, Damin Mutti, is responsible for ZeraBooks’ compliance with this policy and can be reached at daminmutti@zerabooks.com.

2. Our Role

For information about our own customers and website visitors, such as account, billing and usage information, ZeraBooks decides how the information is used and is responsible for it.

Our customers also upload documents and records that contain personal information about other people, such as their own clients, customers, vendors and employees. For that information, our customer decides why it is processed and ZeraBooks processes it on the customer’s behalf to provide the Service. If your information is in books or documents managed by one of our customers, please contact that customer first. If you contact us, we will refer your request to them and help them respond.

3. Information We Collect

Information you provide

  • Account information: your name, email address, company name and sign-in details. Passwords are hashed by our authentication provider and we cannot see them. If you sign in with Google, we receive your name, email address and basic profile information from Google.
  • Billing information: your plan, billing status and the limited billing details our payment processor, Stripe, provides to us. Card details are collected and stored by Stripe. We never receive or store your full card number.
  • Customer Data: the documents and files you upload, import or email to the Service, such as bank, credit card, check and investment statements, invoices, bills, receipts, trial balances and records from previous accounting software, and the books, contacts, invoices, reports and other records you create in the Service. These can include account numbers, transaction details, and the names and contact details of payees, payers, clients and vendors.
  • Ask Zera conversations: the questions you ask the assistant and its answers.
  • Communications: the emails, contact and enquiry forms, call bookings, feedback and feature requests you send us.

Information collected automatically

  • Usage and device information: IP address, browser and device type, operating system, pages viewed, features used, the date and time of activity, and error and server logs.
  • Marketing attribution: how you arrived at our website, such as the referring page, campaign parameters and ad click identifiers. We store these in your browser and add them to your account when you sign up.
  • Cookies and similar technologies: see section 9.

4. How We Use Information

  • To provide the Service, including reading and converting your documents, recording and categorizing transactions, reconciling statements, producing reports and answering questions in Ask Zera
  • To learn from your corrections within your account and each client company, so that later results for that company are more accurate
  • To create and manage your account, authenticate you and manage your subscription and payments
  • To send service emails, such as sign-in and password emails, receipts, notices about your account and bookkeeping follow-ups from Zera, and to send emails and reports that you ask the Service to send
  • To provide support and respond to your requests
  • To provide bookkeeping or enterprise services you have engaged us for
  • To understand how the Service is used and to maintain and improve it
  • To measure the effectiveness of our advertising
  • To protect the Service, detect and prevent fraud, abuse and security incidents, and enforce our Terms
  • To comply with legal obligations and respond to lawful requests

We do not currently send marketing emails. If we do in future, we will send them only as permitted by law, including Canada’s Anti-Spam Legislation, and every marketing email will let you unsubscribe.

We do not sell your personal information or Customer Data, and we do not use Customer Data to train general-purpose AI models offered to others.

5. AI Processing

The Service uses AI models to read documents, extract transactions, suggest and check categories, and answer questions. To do this, the relevant content of your documents and records is sent to our AI model providers, which process it to return results to us. The Service does not use AI to make decisions that produce legal or similarly significant effects about individuals. You review and control the results in your books.

6. Legal Basis and Consent

Canada: we collect, use and disclose personal information with your consent, which may be express or implied from your use of the Service, or as otherwise permitted or required by law. You may withdraw consent at any time, subject to legal or contractual restrictions and reasonable notice. Withdrawing consent may mean we can no longer provide the Service.

EU and UK: where the GDPR applies, we rely on the following legal bases:

  • Contract: processing needed to provide the Service you signed up for
  • Legitimate interests: securing, supporting and improving the Service, preventing fraud and abuse, and measuring our advertising, balanced against your rights
  • Consent: where we ask for it, which you can withdraw at any time
  • Legal obligation: where the law requires us to process information, such as keeping tax records

7. How We Share Information

We share personal information only as described below.

Service providers

We use service providers that process information on our behalf, under obligations to protect it and to use it only to provide their services to us:

  • Supabase: database, authentication and file storage
  • Hosting provider: the servers that run the ZeraBooks application
  • Google: AI processing through the Gemini API, Sign in with Google, Google Analytics and web fonts
  • TypeSafe AI: AI classification used to check categorization results
  • Stripe: payment processing and subscription billing
  • Resend: sending and receiving email
  • Calendly: booking calls with us
  • Advertising platforms such as Meta: measuring the results of our ads, as described in section 9

At your direction

We share information when you ask us to, for example when you email reports or invoices to your clients through the Service, or when you give Authorized Users access to your account. In an enterprise workspace, the firm’s administrators can see the work and data in that workspace.

Legal requirements and protection

We may disclose information where required by law, court order or a lawful request from a public authority, or where we believe disclosure is necessary to protect the rights, property or safety of ZeraBooks, our customers or others, or to investigate fraud or security issues.

Business transfers

If ZeraBooks is involved in a merger, acquisition, financing, reorganization or sale of all or part of its business, information may be disclosed to the parties involved and transferred as part of that transaction, subject to this policy. We will notify you of any change in control of your information.

8. International Transfers

ZeraBooks is based in Canada, and our service providers process information in Canada, the United States and other countries. Your information may therefore be stored and processed outside your province, state or country, where it may be accessible to courts, law enforcement and national security authorities under the laws of that jurisdiction. Where the GDPR applies, we rely on adequacy decisions, including the European Commission’s adequacy decision for Canada, and on safeguards such as Standard Contractual Clauses offered by our providers.

9. Cookies, Analytics and Advertising Measurement

We use cookies, local storage and similar technologies for the following purposes:

Essential

Keep you signed in, protect your account and the Service, and remember choices such as the plan you picked. The Service does not work without them.

Analytics

Google Analytics helps us understand how visitors use our website and the Service. You can opt out with Google’s browser add-on at tools.google.com/dlpage/gaoptout.

Advertising measurement

We record which campaign or ad brought you to our website. When you sign up or start a trial, we may send that event to the advertising platform that showed the ad, such as Meta, together with your IP address, browser information, ad click identifier and a hashed (scrambled) version of your email address, so the platform can tell us whether our ads work.

You can block or delete cookies and local storage through your browser settings. Blocking essential cookies will stop the Service from working properly.

10. Data Retention

We keep personal information only as long as needed for the purposes in this policy or as the law requires:

  • Account information: while your account is open and for a reasonable period afterwards, then deleted or de-identified
  • General Ledger data: your documents and records are kept as part of your books while your account is open, so your history and reports stay complete. You can delete items where the Service allows it.
  • Converter documents: lists in the Converter show the documents uploaded in the last 30 days. Files remain stored on our systems after they leave the lists until your account data is deleted or you ask us to delete them.
  • After your account ends: we may delete Customer Data at any time after 90 days, as described in our Terms of Service
  • Billing records: for as long as tax and accounting laws require, generally at least six years
  • Logs: for limited periods for security and troubleshooting
  • Backups: until they are overwritten in the normal course

We may keep information for longer where needed to resolve disputes, enforce our agreements or comply with a legal obligation. You can ask us to delete your account and data at any time by emailing daminmutti@zerabooks.com.

11. Security

We use administrative, technical and physical safeguards appropriate to the sensitivity of the information, including:

  • Encryption of data in transit using TLS
  • Encryption of stored data by our database and file storage provider
  • Access controls that keep each company’s books separate from every other company’s
  • Passwords hashed by our authentication provider
  • Card payments handled by Stripe, a PCI-compliant payment processor
  • Access to customer information limited to people who need it to provide the Service

We never ask for your online banking login, because the Service has no bank feeds. No method of transmission or storage is completely secure, and we cannot guarantee absolute security. If a breach of security safeguards involving your personal information creates a real risk of significant harm, we will notify you and the relevant regulators as required by law.

12. Your Privacy Rights

Depending on where you live, you may have the following rights about your personal information:

Everyone

  • Access the personal information we hold about you and learn how it is used and disclosed
  • Ask us to correct inaccurate or incomplete information
  • Ask us to delete your account and personal information
  • Withdraw consent, subject to legal and contractual restrictions
  • Complain to us, and to a privacy regulator

EU and UK residents

  • Restrict or object to processing, including processing based on legitimate interests
  • Receive your information in a portable format
  • Not be subject to decisions based solely on automated processing that have legal or similarly significant effects
  • Lodge a complaint with your local data protection authority

California and other U.S. state residents

  • Know the categories and specific pieces of personal information we collect, use and disclose
  • Delete and correct personal information
  • Opt out of the “sale” or “sharing” of personal information. We do not sell personal information for money. Sending signup events to advertising platforms, as described in section 9, may be considered “sharing” under some state laws, and you can opt out by emailing us.
  • Limit the use of sensitive personal information. We use financial account information only to provide the Service.
  • Not be discriminated against for exercising these rights

To exercise any of these rights, email daminmutti@zerabooks.com. We will verify your identity before acting on a request, and an authorized agent may make a request on your behalf with proof of authority. We respond within the time required by law, normally within 30 days. If we cannot fulfil a request, for example because the law requires us to keep the information, we will explain why.

In Canada, you may also contact the Office of the Privacy Commissioner of Canada or, in British Columbia, the Office of the Information and Privacy Commissioner for British Columbia.

13. Children's Privacy

The Service is intended for business use by people who are at least 18 years old. We do not knowingly collect personal information from children. If we learn that we have collected personal information from a child, we will delete it. If you believe we have, please contact us.

14. Third-Party Websites

Our website and the Service may link to third-party websites and services that we do not control. Their privacy practices are governed by their own policies, and we encourage you to read them.

15. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. For material changes, we will notify you by email or by a notice in the Service at least 30 days before the changes take effect. The “Last Updated” date at the top of this page shows when this policy was last revised.
